cannot load net drivers with SP

I have an HP dc7800 The network drivers cannot be loaded or found.
Anyone know how to get this into the system ?

 

Hi Jimbo007, nice green machine,..try HP's instant support/online chat it is very good.

 

Thanks for the replies !
I went to the HP site of course. The drivers are in .exe form and I need one .inf file. I'm not sure where it gets dumpded to if I run the .exe and not sure which .inf it is. I can't run the exe on the 7800 since it's not setup yet and if i run it on another pc I have to know where and what file to look for.
I'll try the chat. I did use that once and it wasn't too bad.
Any ideas on the best way to find THE INF file I would need ?
